An increasingly topical issue nowadays concerns how to ensure vocational training and continuing development courses are used optimally to offer rich knowledge building experiences in and through the practice of working. We start from the basis that this practice incorporates numerous meanings and values (technical, cultural, historical, anthropological, relational, ethical and aesthetic), involves the subject in all its dimensions (mind, heart, limbs, relationships, thoughts, meanings, emotions, etc.) and can contribute to overall human development. A better understanding of work practices and the practical knowledge that can be developed at work lead to a better comprehension of the processes that can facilitate professional development and, in a more general sense, personal and social development too. This course aims to give participants psychological, pedagogical and sociological tools to facilitate adult professional learning in the workplace and in society.
